To. all whom: it may-concern;

Be it known? that I, AnamwnnMnscraeof Bordeaux, France, have in vented aicertain new and; useful Improvement in. Machines for'Makr ,ing Wire (laps, of which the'following is. a

specification This invention is, illustrated; in theaccompanying drawing, i1rwhicl1 Figure 1 represents a sectional side view. Fig. 2zis a plan or top vi'ew. Fig; 31 is-a side View of a wire cap produced by this. machine;

Similar letters indicate corresponding parts.

This invention consists in thexcombination of a forming-die with twistinghooks, in such a manner that, by depressing a wirestar over the forming-die and passing the loose end of said star through its loops, awire cap is produced which can be used for fastening stoppers in bottles. With the forming-die is combined a cup, which is swiveled to a pin that is pivoted to a lever, said cup serving to depress the wire star over the forming-die. The twist in g-hooks are jonrnaled in a common head, and each of said hooks is provided with a pinion, which gears in a central wheel inclosed by the head, so that by turning said central wheel a revolving motion is imparted to the twistinghooks. Two treadles are combined with the cap-forming mechanism-one for elevating the cup, and the other for elevating the die, for the purpose of releasing the wire caps after the same have been completed as far as this operation can be accomplished by the mechanism forming the subject-matter of this present application for a patent.

In the drawing, the letter A designatesa wooden table, on which 1s secured a bed-plate, B, which is provided with a circular guidegroove for the head D, so that said head can be turned in either direction. In the head is contained a conical pinion, G, which turns freely on the arbor O, that extends up through the center of the head, said pinion being connected to a handle, E, which extends out through a slot in the side of the head, and serves to impart to the pinion a partial revolving motion. A spring catchor latch, H, serves to lock the head D to the bed-plate B. The central pinion Gr gears in five pinions, I, mounted on oblique shafts, which have their bearing in the head D,and on the upper ends of which shafts are=formed five hooks, K. A :sixth hook, K, is formed: at the upper end of a rod, L, which is pivoted to the top plate of the head D, and whicl-ris subjected to the action of a spring having a tendency to throw I the same out'away from the center of the head. Athumbpiece formed at thelowerend of the rod L serves to force the hook K inward again s-t'the action of its" spring. arbor (l extends the centralshaft (J, on which is monntedithe forming-die]? at a height above the hooksK K, to correspond to thedepthwhich it. is desired to give to thcwire caps.

This-die is provided on its circumference with six shoulders, toform abutments for the arms of the wire star which is to beformed into a cap,usaid wirestar being formed on a machine describedin a patent granted to me April 13, 1875, and shown in Fig. 4 of the drawings annexed to this present specification. From the forming-die projects a pin, 19, which is intended to catch in the center of the wire star, so as to keep the same in the required position. The shaft 0 rests upon a lever, S, which is situated beneath the table, and which connects with a treadle, B, so that by stepping on said treadle the forming-die is raised up. A spiral spring applied to the shaft 0 has a tendency to keep the forming-die down. Over the forming-die is fitted a cup, T,'which swivels on a pin, U, that is pivoted to the end of a lever, V, so that said cup can freely accommodate itself to the motions of the forming-die. The lever V has its fulcrum in a standard, X, which rises from the table A, and the rear end of said lever is connected to a treadle, Z, so that by stepping on this treadle the cup T may be raised from the forming-die. A spiral spring, a, which acts on the lever V, has a tendency to keep the cup T down upon the forming-die. The standard X forms the bearing for the fulcrum of another lever, b, which extends over the forming-die and the cup T, and is provided with a handle, by means of which the same can be depressed upon the cup. Adouble spring, 0, serves to keep the lever 12 up.

In order to form the Wire caps the cup T is raised by stepping on the treadle Z, a wire star, Fig. 4, is adjusted on the formin g-die P, each of the arms of said star being placed against one of the shoulders of the die. Then Th rough the j the cup T is lowered, and by depressing the hand-lever I) the wire star is depressed over the forming-die, one or two hard blows being given by said hand-lever for the purpose of imparting to the star the required form. The loose end not the wire star is then passed successively round under the hooks K and through the loops 0 of the star, and finally under the hook K, where the same is twisted together with the short wire end a. The head D is then disengaged byreleasing the latch H, and a revolving motion is imparted to it from left to right, and after the latch has again dropped in gear with the head D the handle E is turned from right to left, whereby the hooks K are caused to revolve and to produce the twists 19, Fig. 3. When this operation has been completed the forming-die P is raised by stepping on the treadle It, so that the wire will be stretched, and the wire cap will receive the desired depth and the required shape.

In order to remove the finished wire cap from the forming-die the cup T is raised by stepping on the treadle Z, the rod L is forced in so as to disengage the hook K, the treadle R is released and the forming-die P lowered, and the wire cap can be readily taken off from the hooks K.

The wire caps produced by these operations are finished in another machine, and finally applied to bottles by an apparatus of peculiar construction, both. of which form the subject matters of separate applications for patents, and will be described in their proper places.

I desire to call attention to the fact that the invention claimed in the above entitled application was patented in Great Britain in 1874, and numbered 683.

What I claim as new, and desire to secure lever 12 with the forming-die P and the twisting-hooks K, substantially as set forth.

3. The combination, with the revolving hooks K, their pinions I, and the central pinion Gr, arranged between the same, of the pivoted hook .K, having a thumb-piece, L, and a spring to throw it away from the hooks K, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 24th day of March, 1874.
